To all who/ii it may] concern.-

Be it known that I, vDAnniL MURPHY, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented anew and useful Cotton-Harvester, of which the following is a specification;

My invention relates to improvements in cotton-harvesters, and has for its primary object." the picking of cottonfro n cottonbearing plants.

Further objects are simplicity of construction, effectiveness lH-USB, and the reduction.

of'hand-labor and expense.

In the accompanyingdrawings, forming part of this specification, Figure 1 is a side view of my invention. Fig. 2 is a longitudinal central section of the exhaust-receptacle for the cotton. Fig 3 is an end view of Fig. 1. Fig. 4 is an end view of the cage in the receptacle. Fig. 5 is a longitudinal sectional view of one of the intakes, and Fig. 6 is a detail view of one of said intakes. 7

In a general way, my invention consists of a system of pneumatic cotton-collecting tubes A, which are connected to a portable exhaust-receiverB. Said receiver, as shown, is an oblong box-like structure having at one end a door 2, which is hinged at 3 to the lower wall of said receiver. This door is made to fit tight by means of a gasket 1 and hinged bolts 5, which clamp the door in place by means of thumb-screws 6, bearing against the slotted cli s7, which are fastened on said door. The cut end of the receiver is formed with a platform 8, on which 18 mount ed a gasolene-engine 9 or other sultable motive mechanism which has adrive-pulley 10, connected by a belt 11 with another pulley 12, which is carried by the shaft of an exhaust fan or blower 13. Said fan, as shown, is mounted on the top of the receptacle and has its inlet passage-way 14 connectedthere-. with. A screen or perforated plate 15 is placed over the opening leading into said intake for the purpose of preventing cotton being carried out of said receiver. Near the opening into said inlet passage-way and mounted on the top of said receptacle is a swinging pipe 15*, which is connected by a swiveled joint 16, so that the horizontal por' tion 17, which extends'a considerable dis tance beyond the receiver, is adapted to be swung into any desired horizontal position.

Depending from saidpi-pe-are a lurality of.

flexible tubes 18. to the freeen s of'which Specification of Letters Patent.

Application filed March 18, 1905. I Serial No. 260,722.

rammed Feb. 5, 1907.

are attached intakes 19. Each intake is tapered to reduce the opening at its outer end and is provided with a valve 20, which may be opened by an arm 21. A spring '22, con nected on one end of said arm and on its other with said intake, is adapted to close said valve automatically by means of the coni1ectinglinks 23.

In the receiver B is a'basket C, which is made out of a skeleton. frame 24, having its sides and top lined with wire-1neshing 25. On the bottom of said basket is a lloor, of wood. or other suitable material, and journaled in theclips 26 are a series of antifriction-rollers 27. basket to slide into and out of the receiver with The end of the basket adjoining the door 2 on the receiver is hinged at 28 and adapted to be held closed-by spring-clips 29 on the side walls near the top of the basket The dimensions and shape of the basket closely conform with the dimensions and shape of the walls of the interior of the receiver. The top of the basket hasan opening 32 below the opening leading into the pipe 15.

in use the receiver may be mounted on any suitable truck or wagon, as indicated by.

opened. The pivoted pipe 15 may be swung on either side of the receiver and the intakes directed at will toward any desired point upon the cotton-bearing plants'to remove the cotton therefrom. intake is directed toward'a pod of cotton the valve 20 is opened by pressing the arm 21 toward the end of said intake by means of the thumb or finger. The cotton so removed passes through the flexible tubes 18 and-swinging pipe 15 and into the basket 0. The air admitted by the intakes passes through the inlet passageway 14 and out of the exhaust-blower. The distance between the air inlet and outlet of the passage-way 14 and pipe 15 and the strength of the current of air produced by the blower is such as. when the machine is in operation to cause the cotton to be deposited in, the basket. When the basket C is filled with 'cotton, the

door 2, is opened by lowering it and. thebasket rolled out, and ,carrled away.

These rollei's permit the Each time the em ty basket is then replaced in the receiver an the door 2 again closed and sealed.

Having described my invention, what I claim as new, and-desire to protect by Letters Patent, isv r 1. Apparatus of the class set forth, comprising, in combination, an exhaust-receiver, a 'removablebasket in said receiver, a lurality of antifriction-rollers on said bas et, a swinging pipe connected with said receiver and adapted to turn "on either side thereof, a flexible suction-tube connected with said swinging pipe, and means-for automatically closing said tube.

2. Apparatus of the class set forth, comprising, in combination, a suitable exhaustreceiver, a basket in said receiver, a plurality ofantifriction-rollers on said basket, a hori zontal pipe pivotally connected with said receiver to SW1I1g-0I1 either side thereof, a flexible suction-tube connected with the free end of said pipe, and an intake on the free end of 4. Apparatus of the class set forth, c0m'- ceiver having an inlet, a horizontal pipe pivoted upon said'receiver to swing on either side thereof and having the passage-way f-through its pivot end registering with said .inlet, a series of antifi'iction-rollers on the lower wall of said basket, a plurality of suc tion-tubes .coimected with the free end of said pipe, an intake on each of said tubes, a valve in each intake, an-eXhaust-blower connected with the receiver, a strainer over the inlet leading into said exhaust-blower, and

means for driving said exhaust-blower.

5. Apparatus of the class set forth, comprising, 1n CQIIlblIlitiDlOIl, a suitable receiver, a

door'on said receiver, reans for sealing said door to close said receiver, a reniovable basket in said rece1ver,a plurality of anti friction-rollers on said basketaa suction-pipe pivoted upon the receiver andada ,ted to swing on either side thereof, a. fiexi le'suc; tion-tube connected with the free end of said suction-pipe, an intake on said suction-tube," a valve in said intake, means for automaticallyciosing said valve, and means for exhausting air from said receiver.
